"These magazines work great with my M4CQB open bolt. Did have a problem with the magazines not locking the bolt back on empty but found a fix for it. The spring on the mag catch is weaker than the spring on the bolt catch on the rifle so when the last BB is fired, the mag catch cannot push up on the bolt catch. I removed the spring on the bolt catch on the rifle and now the mags lock back 98% of the time, which is a big deal for me. You can also try shimming the unit where the screw attaches to the shell so that the guts sit a hair higher than normal, but havent tried it, but in theory would work.

"Okay, you'll definitely want to go with the green gas magazines. I bought two of these and now they're for spare parts. Over half of the time that you put in a co2 it will fly out of the top and drain itself. And if that doesn't happen you'll still barely ever manage to shoot all 30 rounds out. And the green gas NEVER fails, no leaks, and it will last about 60 rounds per fill. So save your co2 for pistol mags and grenades.

"My mags would leak and I couldn't get through a whole mag without running out of Co2 I returned the mag and replaced it with a green gas mag and I have had no problem with those mags

Don't get caught without a spare mag in the field. Fill out your kit with extra mags for your Open Chamber PDW or M4. This magazine is specially designed for the WE Open Chamber (a.k.a. Open Bolt) designed PDW, SCAR, ASC and M4 and WILL NOT work with the older (closed bolt) AWSS model PDW or M4. This magazine is a real steel capacity magazine and features a "blank-fire" mode which disables the bolt top function. The "blank-fire" mode is ideal for Military and Law Enforcement training.

Gas Type: CO2 (12 gram cartridge)Capacity: 30 rdsSystem: WE Open Chamber System. Will NOT work with the "close bolt" AWSS system.
